• T3 maintained above TCDE2 for 80 seconds.
• Unit runs for 15 minutes consecutively in defrosting
mode.
Case 2:
• The unit enters defrosting mode according to the
temperature value of T3 as well as the compressor
running time.
• In defrosting mode, the compressor continues to run,
the indoor and outdoor motor will cease operation,
the defrost light of the indoor unit will turn on, and
the “
” symbol is displayed.
• If any one of the following conditions is satisfied,

3.5.5 Evaporator Coil Temperature Protection
• When the evaporator temperature exceeds a preset
protection value, the compressor ceases operation.

• Indoor fan will run at auto fan speed.
• The louver operates same as in relevant mode.
• If the machine switches mode between heating and
cooling, the compressor will keep stopping for certain
time and then choose mode according to
∆
T.
3.7 Drying mode
• In drying mode, AC operates the same as auto fan in
cooling mode.
• All protections are activated and operate the same as
they do that in cooling mode.
• Low Room Temperature Protection
If the room temperature is lower than 10°C, the
compressor ceases operations and does not resume until
room temperature exceeds 12°C.
3.8 Forced operation function
Press the AUTO/COOL button, the AC will run as below
sequence:
Forced auto
→

→
Off
• Forced cooling mode:
The compressor and outdoor fan continue to run and
the indoor fan runs at breeze speed. After running for 30
minutes, the AC will switch to auto mode with a preset
temperature of 24°C(76°F).
• Forced auto mode:
Forced auto mode operates the same as normal auto mode
with a preset temperature of 24°C(76°F).
